Eligibility:

All Genders

1-120 years

Phase:

Eligibility Criteria

Inclusion

  • INCLUSION CRITERIA:
  • History of clinical or genetic diagnosis of NF1 as per the 2021 revised diagnostic criteria
  • Age \>= 1 year
  • At least one digit (finger or toe) without open wounds for application of the device
  • Individuals must understand English or Spanish
  • Individuals who are \< 18 years must have a caregiver willing to help the child engage in study procedures, assist with fitting the AlgometRx Nociometer (Registered Trademark) device, and complete the observer reported (ObsRO) measures. Note: the caregiver of a child participant \>= 5 years old must be able to understand English or Spanish, the caregiver of a child participant 1-4 years old must be able to understand English (to help complete the observational pain measure for the younger children that is only available in English)
  • Ability of individual or parent/guardian to understand and the willingness to sign a written informed consent document
  • EXCLUSION CRITERIA
  • History of eye pathology which precludes pupillometry, such as problems with pupillary reflex, blindness or inability to open at least one eye fully for evaluation
  • Individuals with chronic use of medication that specifically affects their pupillary response, such as atropine-containing eye drops
  • Uncontrolled intercurrent illness evaluated by medical history that would potentially increase in risk of participant
